RENAMEDISK & DELETEDISK through ASMLIB in 11gR2


RENAME/DELETE DISKLABEL through ASMLIB

We can rename a DISKLABEL in asm through two ways

1)      RENAMING BY PROVIDING  DISKLABEL NAME

In the below example, we are rename a disk label by providing the CURRENT DISKLABEL name to NEW DISKLABEL name

[root@ bhuora01]#  /etc/init.d/oracleasm force-renamedisk TEMP5 TEMP6
Renaming disk "TEMP5" to "TEMP6":                          [  OK  ]

 [root@bhuora01]# oracleasm querydisk /dev/mapper/VOTE_05
Device "/dev/mapper/VOTE_05" is marked an ASM disk with the label "TEMP6"

2)      RENAMING BY PROVIDING THE DISK

In the below example, we are rename a disk label by providing the disk and new name to be allocated for the disk

[root@bhuora01]#  /etc/init.d/oracleasm force-renamedisk /dev/mapper/VOTE_05 TEMP5
Renaming disk "/dev/mapper/VOTE_05" to "TEMP5":            [  OK  ]

[root@bhuora01]# oracleasm querydisk /dev/mapper/VOTE_05
Device "/dev/mapper/VOTE_05" is marked an ASM disk with the label "TEMP5"

We can DELETE a DISKLABEL in asm through two ways

1)      DELETE ASM DISK LABEL BY PROVIDING  DISKLABEL NAME

In below example we are check the disk to find the DISKLABEL and we are deleting a disklabel by providing the disklabel name

[root@bhuora01]# oracleasm querydisk /dev/mapper/VOTE_05
Device "/dev/mapper/VOTE_05" is marked an ASM disk with the label "TEMP5"

 [root@bhuora01]# oracleasm deletedisk TEMP5
Clearing disk header: done
Dropping disk: done

2)      DELETE ASM DISK LABEL BY PROVIDING THE DISK


In below example, we are deleting a disklabel by providing the disk and we are check the disk status after deleting the disklabel

[root@bhuora01]# oracleasm deletedisk /dev/mapper/VOTE_05
Clearing disk header: done
Dropping disk: done

[root@bhuora01]#  oracleasm querydisk /dev/mapper/VOTE_05
Device "/dev/mapper/VOTE_05" is not marked as an ASM disk
